    Harrisburg: Severe Storm, Flooding Threat to Precede Cooldown

    The risk of severe thunderstorms and flash flooding will quickly ramp up for the new week.

    As much cooler air plunges into the Midwest thanks to a southward trip by the Polar Vortex, warm and moist air will remain in place through the first part of the week.

    Similar to Saturday, a thunderstorm or two will soak parts of the Harrisburg area again Sunday afternoon.

    Monday through Tuesday, the threat for the thunderstorms to turn severe and drenching will increase. The strongest thunderstorms will produce damaging winds, hail and flooding downpours.


    The upcoming weather pattern is likely to bring extended disruptions to travel and outdoor activities along much of the Atlantic Seaboard, including the South.

    Cooler and eventually less humid air will spread into the region later in the week that can bring some surprisingly low temperatures for the middle of July.

    The weather at Minneapolis early in the week will be more appropriate for football, rather than baseball for the Home Run Derby and the All-Star Game.
